The trees next to the house drop these large nut type things every other year that I've been told are pecans. This year the trees have dropped considerably more nuts than I've ever seen before.
Making things more interesting is that a bunch of them have split open and started sprouting, which is another thing I haven't seen these things do (or noticed anyway).
I planted some of them in some holes I dug around the yard, and the others I left on the ground where they sprouted. Since we won't be here much longer, I won't get to see what happens to them, but hopefully they end up sprouting into saplings and then into trees.
